Enforce supports multiple Active Directory realms. The realms are configured in the krb5.ini file and enabled in the System Settings page.
Excerpt from online help:
- If your environment has more than one Active Directory domain, click Configure and enter the domain names (separated by commas) in the Active Directory Domain List field.
- The system displays Active Directory domains in a drop-down list on the user logon page. Users then select the appropriate domain at logon. Do not list the default domain, as it already appears in the drop-down list by default.
See the online help for your specific installation for complete details on configuring Active Directory.
